Description

Technical Field

[0001] The present invention belongs to the field of measurement and testing technology, specifically relates to the technical field of measuring the physical properties of materials using optical means, and more particularly to a circulator visual detection device and a working method thereof. Background Art

[0002] A microstrip circulator is a unidirectional microwave device designed based on microwave magnetic theory. It is mainly used to control the flow of microwave signals so that they are transmitted sequentially in a fixed direction. It is widely used in communications, radar, satellites, wireless equipment and other fields.

[0003] As the core of the microstrip circulator, the microstrip lead is the transmission carrier of its microwave signal and directly determines the directional transmission characteristics of the circulator. In related technologies, the microstrip lead needs to be aligned with multi-layer structures such as ceramic gaskets and permanent magnets, and the microstrip lead is exposed through the gap in the side wall of the shielding box to ensure signal transmission while preventing external magnetic field interference.

[0023] In an optional embodiment, the front end of the rigid push block is provided with an elastic push block extension hole, and the rear end of the rigid push block is arranged in an inclined surface; and

[0024] The lower end of the extrusion vertical block is also arranged in an inclined surface, and the two inclined surfaces are adapted to each other, so that the extrusion vertical block pushes the rigid push block forward after moving downward.

[0025] In an optional embodiment, a connecting ring is further provided on the top of the extruded vertical block, and the connecting ring is configured to connect several extruded vertical blocks together; and

[0026] The position of the pressure applying portion corresponds to the position of the connecting ring.

[0027] In an optional embodiment, the pressure-applying portion is sleeved on the outside of the negative pressure nozzle, and the bottom surface of the pressure-applying portion is lower than the bottom surface of the negative pressure nozzle; wherein

[0039] If the microstrip lead cannot recover its shape after being squeezed, the microstrip lead cannot contact the protrusion, the circulator cannot be displaced, and a gap is left between the microstrip lead and the negative pressure nozzle, causing the negative pressure to fail and the circulator to be unable to be sucked up.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0056] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0057] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0058] The structure of a microstrip circulator primarily consists of ferrite material, microstrip lines, and a ground plane. Its core typically consists of a central ferrite disk or cylinder surrounded by three microstrip lines symmetrically spaced 120 degrees apart. These microstrip lines are connected to the ferrite disk via metal sheets, forming a closed loop. In addition to traditional electrical performance testing, microstrip leads should also be tested for mechanical properties. Related technologies use visual inspection to test the flatness and phase angle of microstrip lines. However, in actual use, the microstrip leads can be stressed due to equipment vibration and other factors. Therefore, as product quality requirements increase, the strength of the circulator's microstrip leads has also become a parameter that requires testing.

[0059] See also Figure 1 , Figure 1 A circulator visual inspection device is shown, comprising: a workbench 1, on which a conveying track for conveying a circulator 5 is provided; a circulator 5 carrying plate 2, arranged on a bottom rail 11 of the conveying track, and provided with a plurality of circulator 5 accommodating grooves; and an extrusion ring assembly 3, which is configured to apply extrusion to the microstrip lead 50 extending out of the circulator 5; and a visual inspection assembly 4, which is arranged on the top rail 12 of the conveying track; wherein the visual inspection assembly 4 is configured to suck up the circulator 5 in the corresponding accommodating groove and then obtain surface image information of the circulator 5, and judge whether the strength of the microstrip lead 50 of the measured circulator 5 is qualified based on the surface image information.

[0060] In some embodiments, the conveying track is configured to include a bottom rail 11 and a top rail 12, the circulator 5 supporting plate 2 is set on the bottom rail 11, and the visual detection component 4 is set on the top rail 12, both of which are configured to be movable along the corresponding tracks, so that the visual detection component 4 can perform image acquisition and detection on the circulator 5 on the circulator 5 supporting plate 2 in sequence.

[0061] See also Figure 2 、 Figure 3 and Figure 5 Specifically, a plurality of extrusion ring assemblies 3 are further provided on the circulator carrier plate 2, and the extrusion ring assemblies 3 are provided corresponding to the receiving grooves of each circulator 5. The reason for adopting this extrusion method is that the ferrite inside the circulator 5 is a fragile material and is very sensitive to mechanical stress. Therefore, when no extrusion is applied to the microstrip lead 50 of the circulator 5, the extrusion portion 31 in the extrusion ring assembly 3 plays a role in elastically supporting the circulator 5, because the extrusion portion 31 is located at the bottom of the circulator 5, and the microstrip lead 50 of the circulator 5 is in contact with the extrusion portion 31, and a spring is provided at the end of the extrusion horizontal block 311 of the extrusion portion 31 (not shown in the figure). Therefore, if The mechanical vibration generated when the circulator 5 moves along the bottom rail 11 can be absorbed by the spring, thereby preventing the circulator 5 from being subjected to mechanical stress. In the related art, the circulator 5 is fixed by clamping, for example, an elastic gasket is covered on the inner wall of the receiving groove, and then the circulator 5 is clamped in the receiving groove. However, this method has been found to have another significant problem in actual application, that is, when a negative pressure suction nozzle is used to grab the circulator 5, the fit between the circulator 5 and the side wall of the receiving groove causes its friction resistance to be extremely large. This friction resistance will cause a sudden change in tension when the negative pressure suction nozzle sucks. At this time, the tension change will also be transmitted to the inside of the circulator 5, and the ferrite may be damaged.

[0062] In some embodiments, the extrusion ring assembly 3 includes: an extrusion portion 31 and a pressure-applying portion 32; the extrusion portion 31 is arranged on the periphery of the accommodating groove of the microstrip circulator 5, and each extrusion end of the extrusion portion 31 corresponds to the position of the corresponding microstrip lead 50; the pressure-applying portion 32 is arranged at the negative pressure suction nozzle of the visual detection component 4; wherein the applying portion is configured to squeeze the extrusion portion 31 when following the visual detection component 4 to fall to suck the circulator 5, so that each extrusion end of the extrusion portion 31 squeezes the corresponding microstrip lead 50 at the same time.

[0063] See also Figure 2 In this embodiment, the pressure-applying portion 32 is arranged at the negative pressure suction nozzle 42. Therefore, when the negative pressure suction nozzle 42 moves downward, the pressure-applying portion 32 contacts and pushes the extrusion vertical block 312 of the extrusion portion 31 to move downward. After the extrusion vertical block 312 moves downward, it pushes the extrusion horizontal block 311 to move forward. The forward movement of the extrusion horizontal block 311 squeezes the corresponding microstrip lead 50, causing the microstrip lead 50 to be extruded and deformed.

[0064] Specifically, the extrusion cross block 311 includes a rigid push block 315 and an elastic push block 316; wherein the elastic push block 316 is slidably arranged inside the rigid push block 315, and the elastic push block 316 is provided with a protrusion 314 extending from the inside and outside of the rigid push block 315; the rigid push block 315 is configured to push and extrude the microstrip lead 50, and the elastic push block 316 is configured to extend into the bottom of the circulator 5 to lift the circulator 5; wherein the protrusion 314 is configured to move downward when subjected to the extrusion force after the microstrip lead 50 recovers from deformation, thereby allowing the front end of the elastic push block 316 to continue to extend forward to extend into the bottom of the circulator 5.

[0065] As a preferred embodiment, when the circulator 5 is not tested, the circulator 5 is placed in the receiving groove at rest. At this time, the front end of the rigid push block 315 is in contact with the microstrip lead 50. When the circulator 5 is tested, the rigid push block 315 moves forward. Since there is a gap between the vertical end of the microstrip lead 50 and the bottom surface of the circulator 5, the microstrip lead 50 swings and deforms when the rigid push block 315 pushes the microstrip lead 50 forward until the gap between the vertical end of the microstrip lead 50 and the bottom surface of the circulator 5 increases to the allowable gap. The rigid push block 315 is allowed to pass through. If the microstrip lead 50 can immediately return to its original position after the rigid push block 315 passes, it will swing back to its original position. At this time, the vertical end of the microstrip lead 50 will contact the protrusion 314 of the elastic push block 316. At this time, the microstrip lead 50 squeezes the protrusion 314 of the elastic push block 316, and the elastic push block 316 is pressed forward and extends below the bottom surface of the circulator 5, thereby lifting the circulator 5. The top surface of the circulator 5 contacts the negative pressure suction nozzle and can be sucked up by the suction force of the negative pressure suction nozzle. If the microstrip lead 50 cannot return to its original position, the protrusion 314 cannot be triggered, and the circulator 5 will not be lifted, but will continue to be clamped by the rigid push block 315. At this time, there is still a gap between the negative pressure nozzle and the circulator 5, and the circulator 5 is still clamped. At this time, the negative pressure suction force of the negative pressure nozzle cannot suck up the circulator 5. In this way, the strength of the microstrip lead 50 can be applied and detected in real time.

[0066] See also Figure 6 As an optional embodiment, the front end of the rigid push block 315 is provided with a hole for extending the elastic push block 316, and the rear end of the rigid push block 315 is set at an angle; and the lower end of the extrusion vertical block 312 is also set at an angle, and the two inclined surfaces are adapted to each other, so that the extrusion vertical block 312 moves downward and pushes the rigid push block 315 forward.

[0067] As an optional embodiment, a connecting ring 313 is further provided on the top of the extrusion vertical block 312 , and the connecting ring 313 is configured to connect several extrusion vertical blocks 312 together; and the position of the pressure portion 32 corresponds to the position of the connecting ring 313 .

[0068] Specifically, the connecting ring 313 is used to connect several extruded vertical blocks 312 together, so that several extruded vertical blocks 312 can descend at the same speed at the same time. The reason for adopting this method is that the rigid push block 315 is located at the bottom of the circulator 5. The reason for applying pressure here is that this place is far away from the connection between the microstrip lead 50 and the ferrite. Applying pressure is not likely to affect the main resonant structure inside the circulator 5. However, because the rigid push block 315 is located at the bottom of the circulator 5, if it is not squeezed at the same time, the circulator 5 is likely to be unevenly stressed, which will cause the rigid push block 315 to push the circulator 5 to move, and it will not be able to smoothly push the microstrip lead 50 to deform.

[0069] In some embodiments, the pressure-applying portion 32 is sleeved on the outside of the negative pressure nozzle, and the bottom surface of the pressure-applying portion 32 is lower than the bottom surface of the negative pressure nozzle; the distance between the bottom surface of the pressure-applying portion 32 and the bottom surface of the negative pressure nozzle is the same as the front end thickness of the elastic push block 316, that is, after the elastic push block 316 is inserted into the bottom of the circulator 5, the height of lifting the circulator 5 is just enough to make the circulator 5 contact with the negative pressure nozzle.

[0070] As an optional implementation, the negative pressure suction nozzle is a vacuum type negative pressure suction nozzle, that is, the circulator 5 needs to be in contact with the suction cup of the negative pressure suction nozzle to achieve the negative pressure effect.

[0071] In some embodiments, the visual inspection assembly 4 includes a 3D scanning camera 41; a negative pressure suction nozzle disposed on the front sidewall of the 3D scanning camera; and a cylinder 43 connected to the front sidewall of the 3D scanning camera. The cylinder drives the negative pressure suction nozzle up and down to grasp the circulator 5 for image capture by the 3D scanning camera.

[0072] Specifically, the reason why images of the circulator that can be sucked up are also captured to further determine the strength of its microstrip leads is that the extrusion ring assembly 3 is used to apply pressure to the microstrip leads of the circulator, the circulator that cannot be restored is clamped, and the circulator that can be restored is normally grabbed, which only realizes the simulation and initial inspection of the strength. Since the protrusion width of the elastic push block is greater than the width of the circulator microstrip leads, there will still be some circulators that are lifted up but the recovery amount of their microstrip leads is still slightly insufficient. In this regard, visual inspection is used to perform a more detailed inspection, and the captured image is compared with the standard image to determine whether the strength of the circulator microstrip leads is qualified. In addition, the image acquisition and analysis methods include but are not limited to the image acquisition and analysis methods in the prior art.

[0073] On the other hand, this embodiment also provides a working method of a circulator visual inspection device, including: using the above-mentioned circulator visual inspection device; and grasping the circulator 5 through a negative pressure suction nozzle; capturing an image of the grasped circulator 5 through a 3D scanning camera; and comparing the captured image with the standard image to determine whether the quality of the grasped circulator 5 is qualified.

[0074] Specifically, the method for grabbing the circulator 5 by the negative pressure suction nozzle includes: when the negative pressure suction nozzle moves downward, the pressure-applying portion 32 arranged on the outside thereof first pushes the extrusion portion 31 to squeeze the microstrip lead 50 of the circulator 5; wherein if the microstrip lead 50 can still recover its deformation after being squeezed, then the microstrip lead 50 will contact and squeeze the protrusion 314 of the elastic push block 316, so that the front end of the elastic push block 316 extends forward to extend to the bottom of the circulator 5 to lift the circulator 5, thereby making the negative pressure suction nozzle contact with the top wall of the circulator 5, thereby sucking up the circulator 5; if the microstrip lead 50 cannot recover its deformation after being squeezed, then the microstrip lead 50 cannot contact the protrusion 314, the circulator 5 cannot be displaced, and a gap is left between it and the negative pressure suction nozzle, so that the negative pressure fails and the circulator 5 cannot be sucked up.

[0075] In summary, the circulator 5 visual inspection device carries and transports several circulators 5 to be tested through the circulator 5 carrying plate 2, applies compression to the microstrip lead 50 of the circulator 5 through the extrusion ring assembly 3, and performs different treatments on the circulator 5 according to the degree of recovery of the microstrip lead 50 after being squeezed. If the microstrip lead 50 cannot recover the deformation, the elastic push block 316 of the extrusion ring assembly 3 cannot be triggered, which causes the circulator 5 to be unable to be pushed upward, and the adsorption force of the negative pressure suction nozzle cannot be satisfied, and the circulator 5 cannot be sucked up. If this problem occurs for the circulator 5, it can also be determined that the strength of the microstrip lead of the circulator 5 is unqualified, and there is no need for subsequent visual inspection. The extrusion ring assembly 3 realizes the simulation of the strength of the microstrip lead 50 of the circulator 5 and the recovery detection after application, thereby improving the detection efficiency and the detection accuracy.
